From the pan S the dried acetate of lime may be removed by opening' the door S? and dropping it n'tobarr'els or other suitable receptacles.

My improved process of manufacturing acetate voi' lime does not" require the acct-ate to be separatori from the base by dissolving in Water and evaporating, after the base has been thor oughi permeated with pyroligneous-acid impers. Nor is there any loss of suoli pyroiigiieous acid, as all. its particles are utilized, the luid from the ireservoirW' containing considerable alcohol, &c., which by proper distillation, may be easily separated. Bymy process I am enabled to produce )'iertect acetate of lime at one operation.

Having described my invention, I claimi.. In. the manufacture of acetate of lime at one operation, the vapors of pyroligneous acid and slaked lime, or their equivalents, introduced into direct contact with' each other while in a state of commet-.iai essentially as described.

2. In the manufacture of acetate of linie, the charging of slaked lime with pyroligncous-:icid vapors in an agitator, substantially as described.

3. In the manufacture of acetate of lime, tile process of condensing the empyrcumaticated vapors formed in the production of the acetate of linie, to utilize its iiuid and gaseous matter, substantialiy'as described.

4.. In combination. with the pipe for conducting the pyroligneous acid from the still, thc iuclosingcas6 or cylinder K for said pipe, to render 'the heat uuiform'and to protect the conveyingpipe, as described.

' fo. In combination-With a boiler for evaporizing pyroligneous acid and a superheating-uL nacc,a1 1 agitator, L T T1, substantially es lescm'bed.

6. Iif'combination with the agitator, a feedingconveyer, N, substantially as described.

7. In combination withtheagitator, the loubliL bottomed pan S, substantially as described.

8; In combination with. the agitator and pan S, the space S1, pipe L', condenser U U', reservoir W', and pipes WV ir, substantially as described.

In testimony whereof I have hereunto set my hand to the above specification of my improxgcment in the manufacture of acetate of lime from pyroligneous acid, this 6th day of July, A. l). 187i, in the presence of two witnesses.
